F3 .15: 1 17.15. F3 15. 6: o 3 6 59 7a W/ZMM in the usual way with a hub 27, actuating a yoke or knob shoe 28, which retracts the latch bolt in the customary manner by engaging a crosshead 29 on the latch bolt stem.

The dead bolt 22 isprovided with a shank portion 30, having a slot 31, by means of which the bolt is guided on a fence or post 32 cast on the back of the case. The bolt shank is also provided with a slot 33 to clear the thumb turn hub 24, which is mounted to oscillate between the back of the lock case and the ca plate, as usual. At is lower rear portion, t e shank 30 of the dead bolt is provided with a longitudinal groove 34, by means of which the bolt is guided on a fin 35 cast on the back of the case. The bolt is provided with a primary tumbler 36, shown in detail in Fig. 10, said tumbler ivoted on a post 37 carried by the dead olt and bein actuated by the usual spring 39, supported against a ug 4O lprojecting outward from the bolt shank. t its rear portion, the tumbler 36 is provided with a loop 41 extending around the hub 24. On the upper part of this loop 41 is an operating projection 42, which is normally locate between the talons 43 on the upper part of the bolt shank, which talons are adapted to be engaged by certain parts of the cylinder lock 23, for the purpose hereinafter described. As shown in Fig. 9, the talons 43 are wider than the projection 42 of the primary tumbler 36. On the upper edge of tumbler 36 is a lug 44 adapted to engage the fence or stump 32 so as to lock the bolt in the protracted or retracted position. A secondary tumbler 45 is mounte on the bolt alongside the primary tumbler 36, said secondary tumbler being pivoted on the same post 37 and being also provided with a spring 46 sup orted against the lug 40. Furthermore, t is secondary tumbler 45 is rovided with a loop 47, overlying the 100 E1 of the primary tumbler around the thum turn hub, and provided at its upper part with an operating projection 48 closely adjacent to theoperatmg projection 42 within the space between the talons 43 of the dead bolt. The secondary tumbler is provided at its lower part with an outwardly projecting pin 49 ada ted to engage a recess or socket 50 in the ower part of the loop 41 of theprimary tumbler so that while the primary tumbler may be independently actuated, the depression of the secondary tumbler will cause the primary tumbler to be depressed at the same time for the purpose hereinafter described. When thesecondary tumbler is actuated, a pro ection 51 on the lower rear part thereof is adapted to pass beneath a gulde lug' 52 on the case.

Instead of having a fixed lug or abutment to cooperate with a fence or stump on the case, the secondary tumbler 45 is provided with a movable abutment member 53 whicg, in this case, coii crates with the fence 3 However, while' have shown the movable abutment member 53 cooperating with the same fence which looks the primary tumbler, this is not an essential feature in all aspects of the invention. The movable abutment member is pivoted to the secondary tumbler by a pivot pin 54, said abutment member being in the form of an upwardly extending lever applied to the outer face of the secondary tumbler and having its upper extremity projecting above the upper edge of the secondary tumbler, as shown clearly in Fig. 11. In the present case, the upper end of the abutment member is in line .with the lug 44 of the primary tumbler when the parts are in the position shown in Fig. 1. The abutment member is adapted to swing on the pivot 54 in opposition to a spring 55, which is connected with said member and supported against the pin 56 on the secondary tumbler. The spring 55 opposes swingmg movement of the member 53 in the direction of the pin 56, and a similar pin 57 at the opposite side of the abutment member limits movement thereof in the opposite direction. The arrangement is such that when the parts are. in the position shown in Fig. 1, the abutment member 53 will offer no appreciable resistance to the protraction of the bolt, and therefore the secondary tumbler 45 can be pulled forward with the bolt without depression of said secondary tumbler owing to the fact that the spring 55 permits the member 53 to yield and move out of the Way of the fixed fence 32 as the bolt is being projected. Under these circumstances, the upper extremity of the movable abutment 53 is still in contact with the lower surface of the fence 32 when the dead bolt reaches its fully protracted position, as shown in Fig. 6, and therefore the member 53 cannot pass up into a position in front of the fence for locking the bolt in protracted position by means-of the secondary tumbler. When, however, the secondary tumbler is given a full depression, the member 53' may he. swung clear of the fence 32 and up into the locking position in front of the fence, as shown in F 1g. 2.

Referring now to the construction of the cylinder lock 23, the cylinder casing 58 is of the usual construction, having the face plate or escutcheon 59, a pin tumbler housing 60, and the usual threaded rear portion engaging a threaded hole in the capof the lock case. The key plug 61 having the usual keyway is rotatable in a bore through the cylinder, and is somewhat longer than the cylinder so that it projects out of the latter at the rear end. This key plug 61 is adapted to be locked to the casing 58 by the usual sectional pin tumblers 62. Surrounding the rear portion of the key plug is a concentric over the flange ortion 71, and the primary rollback is tien secured to the rear end of the key plug by screws 76. The rollback 65 has an opening 77 adapted to fit closely over a short integral extension 78 on the rear end of the key pin 61, and when the rollback 65 has been p aced over this extension it will abut the rear face of the key plug at 79, and it will also abut the rear face of the washer 75, and the rear face of the flange, which are flush with the surface 79 of the key plug. It will be understood, therefore, that when the rollback 65 is secured in place by the screws 76, the emergency rollback will be clamped in place against the shoulder of the sleeve and held against rearward displacement by the spacing washer and the primary rollback.

It will be observed that the sleeve 63 rotates about a reduced portion 80 at the rear of the key plug. and that the sleeve is provided with a rabbet 81 at the front inner part. At the lower part of the sleeve, a groove 82 is cut fro-m the rabbet 81 to the lower recess 72, and this groove 82 is adapted to be engaged by the inner extremity of the emergency key when the latter is inserted into the cylinder look, as shown more particularly in Fig. 530. In this manner, the emergency key is locked directly to the sleeve, and it is not necessary for the sleeve to be carried from the key plug by the pin 62. In this manner, the pin tumbler 62 is relieved of strain.

When the dead bolt is protracted from the inside of the room by the thumb turn, or from the outside of the room by the emergency key, the knob mechanism is dogged automatically by a swinging dog 83, pivoted at 84k, and adapted to block the operation of the knob shoe 27 by occupying a position back (if a shoulder 85 on sand shoe, as shown in Fig. 4:. When the dead bolt is protracted by the thumb turn, for example, the secondary tumbler is depressed to such an extent as to engage the u per end portion 86 of? the do -83, and shi said dog from the position s own in Fig. 1 to that shown in Fig. 4, which is the dog ing position. The lower, part of said secon ary tumbler is provided with' a forked portion 87 adapted to straddle thesupper part of the dog 83, and to SWingilt on its pivot to dog and release the .knob' shoe when the bolt is protracted or. retracted respectivel by means which cause a full depression 0 the secondar tumbler; but when the bolt is protracted y the change key, the secondart'y tumbler is not depressed, and therefore e dogging member 83; is unafiected.

Various changes may be made in the details of the construction without departing from the scope of the invention as defined .in the claims.

I do not claim broadly herein the combination of a dead bolt, a fence, a plurality of tumblers pivoted to said bolt so as to be carried thereby, one of said tumblers having a rigid shoulder or abutment to cooperate with said fence, and another tumbler-having a movable shoulder or abutment to cooperate with said fence and means for actuating said tumblers and protracting and retracting the bolt, as claimed in my application Serial N 0. 14,124, filed March 13, 1915.
